COLOR? Script for rule in mail to mark words in color

Scripting Forums AppleScript | Mac OS X

Hi,

I was trying to get Mail to perform the following:
-copy mails from a certain source in to a couple of submailboxes according to keyword content
-then highlight the keywords that triggered the copy with certain colors

The first is obviously easy using just rules. For the second I have attempted the following script:


using terms from application "Mail"
	on perform mail action with messages message_list for rule this_rule
		set targetdir to name of (copy message of this_rule)
		repeat with this_message in message_list
			if targetdir is equal to "workspace" then
				set numberofwords to 2
				set targetwords to {"bugger", "test"}
				set markingcolor to {red, blue}
			end if
			set WordCount to (count words of content of this_message)
			--display dialog "WordCount: " & WordCount buttons {"OK"} default button 1 with icon stop
			repeat with counter from 1 to WordCount
				set currentword to word counter of content of this_message
				repeat with counter2 from 1 to numberofwords
					set comparisonword to item counter2 of targetwords
					if currentword is equal to comparisonword then
						display dialog "triggered! " buttons {"OK"} default button 1 with icon stop
						set color of word counter of content of this_message to red
                                                -- later plan: set color of word counter of content of this_message to item counter2 of markingcolor
						--test:
						set currcol to color of word counter of content of this_message
						display dialog "currcol! " & currcol buttons {"OK"} default button 1 with icon stop
					end if
				end repeat
			end repeat
		end repeat -- message loop
	end perform mail action with messages
end using terms from

It seems to work mostly as anticipated, except that setting the color does not seem to have any effect.
Can I just not do this at all? Or do I do it wrong?

Thanks in advance for any help,

Sebastian
